5 cT • Closely allied to and resembling S. hidipeatus, but con- 

 stantly larger. It is a very variable insect, but the type has the 

 head, thorax, and abdomen very minutely punctured, with a very 

 fine short erect hair springing from each puncture ; clypeus much 

 broader than high, slightly convex, pointed laterally, widely eraar- 

 giuate in the middle anteriorly ; the enclosed space at the base 

 of the median segment semicircular, with a short medial longi- 

 tudinal furrow continued down the posterior truncated face of the 

 segment to the apex. Rufo-fulvous, the base of the mandibles, the 

 labrum, clypeus, antennae in front, cheeks, pronotum, postscu- 

 tellum, an arched stripe on the median segment, a large rounded 

 lateral spot on the 2nd, and an elongate lateral spot at the base 

 of the 3rd abdominal segment yellow ; legs variegated with yellow ; 

 wings deep flavo- or fulvo-hyaline, with a subapical fuscous cloud 

 on the fore wing. 



Tar. A broad T-shaped mark on the vertex and front of the 

 head, a broad longitudinal stripe on each side on the mesonotum, 

 joined by a transverse stripe anteriorly, an arched stripe on the 

 ruedian segment, the propleurse, the mesopleurse posteriorly, the 

 metapleursB and sides of the median segment, and broad trans- 

 verse bands on the basal four segments of the abdomen black. 

 Between these two extreme forms numerous variations in the 

 amount and disposition of the yellow and black markings occur. 



Hah. Throughout India south of the Ilimalayiis, not ascending 

 the hills to any height ; Ceylon ; Burma ; China. $ S ■ Length 

 20-25 ; e.rj). 40-48 mm. 



I have wholly failed to make out Guerin's species S. delessertii ; his 

 description would stand faii'ly well for one variety of Smith's species.
